This paper has several aims: to determine if Yersinia pestis was the causative agent in the last Scottish plague outbreak in the mid-17th century; map the geographic spread of the epidemic and isolate potential contributing factors to its spread and severity; and examine funerary behaviours in the context of a serious plague epidemic in early modern Scotland. Results confirm the presence of Y. pestis in individuals associated with a mid-17th century plague pit in Aberdeen.

PAS kinase is a sensory protein kinase associated with many of the phenotypes of these diseases, including hepatic triglyceride accumulation and metabolic dysregulation in male mice placed on a high-fat diet. Herein we provide the first characterization of the effects of western diet (high-fat high-sugar, HFHS) on Per-Arnt-Sim kinase mice (PASK) and the first characterization of both male and female PASK mice.

Transmission electron micrographs showed an increased number of mitochondria in PAS kinase-deficient yeast consistent with the increase in respiration.

Bacteriophages that infect the Enterobacteriaceae family are of particular interest because this bacterial family contains dangerous animal and plant pathogens. Herein we report the isolation and characterization of two jumbo myovirus Erwinia phages, RisingSun and Joad, collected from apple trees.
